Catenation of Loop-Containing 2D Layers with a 3D pcu Skeleton into a New Type of Entangled Framework Having Polyrotaxane and Polycatenane Character

Catenation of 2D layers of rings with a 3D frame of pcu topology gives a new type of entangled framework incorporating functional, nanosized polyoxoanions, which exhibits both polycatenane and polyrotaxane character.
